This subreddit is exclusively for pictures of infrastructure. Paved roads and other public transit, agriculture, freight, waste management, and water systems are all things we could live without but we really don't want to (and they look cool too!). For some examples of infrastructure as well as a definition see this.

If you took the photo yourself, you can signify this by using the tag [OC] (original content) and after 24 hours you will be given special flair. If you don't receive flair after a few days feel free to message the mods.
